Sam Whiles joins for some chat about "Back To The Egg", but primarily one of the few interviews Paul did for "Back to the Egg".   James McCartney was not quite two years old, Wings was settling into the outfit that would become the final iteration, and Paul was toying around with tunes that would become "McCartney II".    Also found in this episode is news that is slightly out of date (will that matter in a year, month or even a week?)
